Since 2000, CathPro has engineered sacrificial anode systems for pipelines, offshore platforms, and storage tanks across more than 40 countries. DNV type-approved. Contributor to five Chinese national standards. Quiet metallurgy, measurable results.
Focused solely on sacrificial anode metallurgy since 2000.
Verified electrochemical capacity — Al-Zn-In series exceeds GB standards.
Supplied to pipeline, marine, and storage projects on five continents.
Test-station line automation — zero hand-soldering variance.
Every anode we ship begins as raw ingot, traceable to the melt. Composition, casting, post-processing — all performed in-house, under ISO 9001 and DNV type-approval oversight.
Soil, freshwater, buried pipe, tank bottom.
Seawater, brackish water, offshore structures.
Marine grounding, ribbon anode, heat-exchanger.
Test stations, gel reference electrodes, rectifiers.
In our trade, reputation is built underground and underwater — in the places no one sees. We chose to stay in a narrow lane: sacrificial anodes. No diversification. No shortcuts.
Twenty-five years of the same work, refined a thousand times. Every anode carries an ingot trace, a chemistry report, a signed inspection.
“In the unseen, conscience is the only witness.” — CathPro Operating Principle
In-house melt control and impurity management hold the electrochemical capacity of our Al-Zn-In series consistently above 2700 A·h/kg — measurably beyond the Chinese national standard floor.
Proprietary heat-treatment retains flexibility at −30 °C. Ordinary zinc ribbon embrittles and cracks; ours lays straight out of the reel through a deep-winter install.
The test-station line runs at 90 % automation — sheared, punched, terminated, and pressure-tested by machine. No two stations differ by human hand.
High-stability gel electrolyte eliminates leakage and dry-out. Bury it once, read it true for ten years. Backed in writing.
Type-approval, classification certification, and national-standard authorship. CathPro is a contributor to five GB standards and an active member of the Cathodic Protection Committee of the China Corrosion and Protection Society.
Pipeline integrity, platform retrofit, tank-bottom protection — share the environment, the geometry, and the timeline. Our engineers reply within one business day, in English, Arabic, or Mandarin.
